Are there 40 time zones in the world? ›

Other nations, such as Nepal, use quarter-hour deviations. This means that there are approximately 40 time zones rather than 24.

Time zones and time differences

There are 24 regions (Time Zones) around the world with a time difference of one hour. This system has been adopted internationally by setting the total time difference around the world as 24 hours. Further, Daylight Saving Time (DST) is individually adopted in countries and regions.

More Than 24 Time Zones

Also, the International Date Line (IDL), creates 3 time zones and several time zones are only 30 and 45 minutes apart. This makes the total number of time zones worldwide much higher.

In May 1996, the government, faced with a major electricity crisis, changed standard time to GMT+6:30 then readjusted it to the more convenient GMT+6 a few months later. Some conservative Sri Lankans never accepted the change. This resulted in a hilarious situation of 'old time' and 'new time' coexisting for a decade.

So why are some cities 30 or 45 minutes off? That has largely to do with the politics in each of those places. For example, in New Delhi, India, they found themselves halfway between two meridians, and therefore decided to be 30 minutes between each, as opposed to adopting one time or the other.

None if you compare time with all the USA 50 States. American Samoa is the only contender for the comparison year round and Kiribati, Tonga as well New Zealand (for Tokelau) are all 24 hours ahead of American Samoa all year round.

Ideally, time zones would be slices of Earth's surface 15 degrees of longitude wide that keep the same time. However, some countries and parts of countries have decided that being within a specific time zone is not preferable and have chosen offsets of 30 minutes or even 45 minutes.

One of the most unusual time zone offsets is Nepal, which is fifteen minutes behind neighboring Bangladesh, which is on a standard time zone. Nearby Myanmar (Burma), is a half-hour ahead of Bangladesh but an hour ahead of offset India.

The United States consists of 50 States and the District of Columbia. The capital is Washington, District of Columbia; the largest city by population is New York, New York.

How many time zones does USA have? ›

Currently the United States and its territories have 9 time zone boundaries: Atlantic, Eastern, Central, Mountain, Pacific, Alaska, Hawaii–Aleutian, Samoa, and Chamorro.

For any given date, the latest place on Earth where it would be valid is on Howland and Baker Islands, in the IDLW time zone (the Western Hemisphere side of the International Date Line). Therefore, the day ends AoE when it ends on Howland Island.

The maximum time difference between U.S. states is six hours. That is the difference between Eastern Daylight Saving Time (EDT; UTC-4) and Hawaii-Aleutian Standard Time (HAST; UTC-10). 17 U.S. states are at least partially on EDT from March to November. Hawaii is always on HAST.

Owing to the number of territories it governs beyond Europe, France has 12 (and for a period of the year 13) time zones. Metropolitan France operates on Central European Summer Time (UTC+2), while its dependencies range from Tahiti Time (UTC-10) in French Polynesia to Wallis & Futuna Time (UTC+12) in the South Pacific.

We all have 24 hours in our day, but there are 38 time zones observed across the world offset from Coordinated Universal Time (UTC), and each country gets to pick the one it aligns with.

UTC is a time standard, not a time zone. No country “uses” UTC, but every country's time is based on UTC. Today, there are 37 time zones in use, and they often don't match up with their actual lines of longitude, but follow national and international borders.

The total is 40 if you don't count UTC-12, the time zone of Baker and Howland Islands, which are officially uninhabited. Some time zones, UTC-3:30, UTC-2:30, UTC+3:30, UTC+12:45, and UTC+13:45, are in use during only part of each year due to Daylight Saving Time (a.k.a. Summer Time).

In Russia, there are eleven time zones with current times ranging from UTC+02:00 to UTC+12:00. Since October 26, 2014, Russia has not used daylight saving time (DST). Permanent DST was used from March 27, 2011 to October 26, 2014.
